T1190, T1133, T1071

Legitimate administrative access to H3C device management interfaces, routine firmware updates or configuration changes via /goform/ endpoints, and normal web application file operations may trigger alerts. Whitelist known management IPs, scheduled maintenance windows, and authenticated administrative accounts. Filter out internal network scanning and vulnerability assessment tools that may probe these endpoints.

CVE-2026-6560 is a critical remote buffer overflow vulnerability in H3C Magic B0 devices affecting the Edit_BasicSSID function in /goform/aspForm, with a CVSS score of 8.8. Detection should focus on identifying exploitation attempts targeting H3C devices through malicious web requests and subsequent process execution or network anomalies.

let timeframe = 7d; let h3c_indicators = dynamic(['Edit_BasicSSID', 'aspForm', 'goform']); union (DeviceNetworkEvents | where Timestamp > ago(timeframe) | where RemoteUrl has_any (h3c_indicators) or InitiatingProcessCommandLine has_any (h3c_indicators) | project Timestamp, DeviceId, DeviceName, RemoteIP, RemoteUrl, RemotePort, InitiatingProcessFileName, InitiatingProcessCommandLine, ActionType), (DeviceProcessEvents | where Timestamp > ago(timeframe) | where ProcessCommandLine has_any (h3c_indicators) or FolderPath has_any (h3c_indicators) | project Timestamp, DeviceId, DeviceName, ProcessCommandLine, ProcessId, FileName, FolderPath, AccountName, ActionType), (SecurityEvent | where TimeGenerated > ago(timeframe) | where Activity has_any (h3c_indicators) or CommandLine has_any (h3c_indicators) | project TimeGenerated, Computer, Activity, CommandLine, Account, EventID) | where ActionType !in ('ProcessTerminated', 'NetworkConnectionTerminated') or Activity !has 'Success' | limit 1000

Monitor for HTTP requests containing Edit_BasicSSID, aspForm, or goform path indicators targeting H3C devices. Correlate with subsequent suspicious process creation, command execution, or unexpected network connections from affected devices. Focus on remote connection attempts to H3C management interfaces and buffer overflow exploitation patterns in request payloads.

CVE-2026-6577 affects DjangoBlog up to version 2.1.0.0, introducing a missing authentication vulnerability in the logtracks endpoint (owntracks/views.py) that allows unauthenticated remote access. Detection focuses on identifying suspicious web requests to DjangoBlog instances, particularly targeting the vulnerable owntracks endpoint, combined with process and network indicators of exploitation.

let timeframe = 7d; let djangoblog_paths = dynamic(['/owntracks/', '/logtracks', 'owntracks/views.py']); union (CloudAppEvents | where TimeGenerated > ago(timeframe) | where ActionType in ('HttpRequest', 'WebRequest') | where any(djangoblog_paths, p => RawEventData has p or Url has p) | project TimeGenerated, AccountId, Url, ActionType, RawEventData, DeviceName), (DeviceNetworkEvents | where TimeGenerated > ago(timeframe) | where RemoteUrl has 'djangoblog' or RemoteUrl has 'owntracks' | where ActionType == 'ConnectionSuccess' | project TimeGenerated, DeviceName, RemoteUrl, RemoteIP, RemotePort, InitiatingProcessFileName, InitiatingProcessCommandLine), (DeviceProcessEvents | where TimeGenerated > ago(timeframe) | where ProcessCommandLine has_any ('django', 'python') and (ProcessCommandLine has 'owntracks' or ProcessCommandLine has 'logtracks') | project TimeGenerated, DeviceName, ProcessCommandLine, ProcessId, AccountName, FileName) | summarize EventCount = count(), UniqueDevices = dcount(DeviceName), EventTypes = make_set(ActionType) by bin(TimeGenerated, 1h), DeviceName | where EventCount > 3 | limit 1000

Detection correlates three signal types: (1) CloudAppEvents for HTTP requests targeting owntracks/logtracks endpoints without proper authentication context, (2) DeviceNetworkEvents for network connections to DjangoBlog instances from unexpected sources, and (3) DeviceProcessEvents for suspicious Python/Django process execution with owntracks/logtracks references. Aggregation identifies devices with multiple related events within 1-hour windows, indicating potential exploitation attempts.

Legitimate DjangoBlog administrators accessing owntracks endpoints for maintenance, automated monitoring tools querying the logtracks endpoint, and development/testing environments running DjangoBlog locally. Tune by excluding known admin IP ranges, internal monitoring tools, and development subnets. Consider allowlisting authenticated service accounts and known CI/CD pipelines.
